computer very laggy after game play

my iBook seems to get very laggy after playing Halo for say an hour. to the point where i litterally cant play anymore. even after i quit the game, its still laggy. just happened to me a couple minutes ago so im gonna try restarting the computer.

also i know that my computer needs more RAM for Halo to function properly. i only have 256mb RAM but this problem doesnt seem to be a RAM problem. does anyone know what could be wrong?

*edit* 10 minutes later, without restarting, my computer seems to be better. could it be a problem with overheating? the fan didnt go on and my A/C is on.

It's probably ram related. Your ram is "full" with stuff from Halo, or another game, and needs to clear this first. This doesn't happen immediatly, but takes a minute of ten. My brother in law has a progrom for it on his windoos pc. I believe it's from Norton, which monitors everything. It overwrites the ram that was used from the program that was shut down.
